Disclosed are a method and corresponding apparatus to operate transmitting and receiving nodes processing a packet including field position information. The packet includes field position information. Provided is the method for operating a transmitting node, including generating a packet comprising location information indicating information about a location corresponding to a field in the packet, and transmitting the packet including the position information.

A method of estimating a round-trip time (RTT) is provided. The method may include providing content requested by an interest packet with an identifier to identify a second node that sends the content to the first node, determining a processing time (PT) in which an interest packet is processed in the second node, based on an arrival time in which the content is received by the first node, evaluating an instantaneous RTT for the content received by the first node, based on an arrival time in which the content with the identifier is received at the first node, a sending time in which the interest packet is sent to the second node, or the determined PT, and estimating an RTT for the interest packet based on the evaluated instantaneous RTT.

Method of estimating round-trip time (RTT) in content-centric network (CCN)

A method of transmitting a data packet from a content provider in a content-centric network CCN includes verifying whether a content request packet requesting a content identical to a content of a content request packet being received from a content requester is present in a pending interest table (PIT), increasing a value of a counter corresponding to the content request packet, comparing the value of the counter to a predetermined threshold value, and transmitting a data packet using a predefined broadcast media access control (MAC) address in response to the content request packet being received and the value of the counter being greater than or equal to the threshold value.

Transmitting a data packet in a content-centric network

A method of communication for a terminal in a content-centric network is provided. The method includes suspending a data message associated with a content from being provided to a face before a handover when the handover is expected to occur in the terminal that requests the content, and transmitting, to a hub, a new interest message after the handover associated with the content so that the hub may provide the data message associated with the content to the face after the handover.

A method and apparatus to process interest messages and data messages based on priorities in a Content-Centric Network (CCN) are provided. The method and apparatus to process interest messages and data messages based on priorities in a CCN provides different Quality of Service (QoS) based on type of contents by extracting a traffic type of each of the contents.

A node and a method for generating a shortened name robust against a change in a hierarchical name in a Content-Centric Network (CCN) are provided. The method includes receiving a packet requesting content including a hierarchical name of the content, and determining whether a prefix of the hierarchical name is identical to a name of the node. The method further includes generating a shortened name by removing the prefix from the hierarchical name if the prefix is identical to the name component, and changing the hierarchical name to the shortened name. The shortened name is used to check whether the corresponding content is stored in the content cache, to check whether the same content-request packet is already under processing, and to decide an outgoing face to which the content-request packet is transmitted.

Node and method for generating shortened name robust against change in hierarchical name in content-centric network (CCN)

A content sharing method of an intermediate node based on a content oriented network (CON) is provided. The method includes receiving, from a content requesting terminal, a proxy sharing request message with respect to a content including a content name of the content, the content including a plurality of data segments, generating data segment request messages with respect to each of the plurality of data segments corresponding to the content, in response to the reception of the proxy sharing request message, transmitting the data segment request messages to at least one terminal having the plurality of data segments, receiving the plurality of data segments from the at least one terminal, and transmitting the content to the content requesting terminal, using an aggregated data transmission scheme based on the received plurality of data segments.

Provided is a method of controlling a home hub in a virtual group that may provide a geographical boundary about the virtual group by associating an identifier of a network of a virtual group included in an access point list with a name of the virtual group and a name of the home hub managing the virtual group, and may provide a terminal which moves to a visited virtual group with information about a network of the visited virtual group, thereby facilitating recognition of a virtual group and content sharing.
